Abstract
Official abstract text for this publication.
This invention relates to electroluminescent metal complexes of the formula (I) wherein the ring A, represents an optionally substituted aryl group which can optionally contain heteroatoms, the ring B, represents an optionally substituted nitrogen containing aryl group, which can optionally contain further heteroatoms, or the ring A may be taken with the ring B binding to the ring A to form a ring; the group C, represents an acyclic carbene, or a cyclic carbene (ring C), which can optionally contain heteroatoms, the ring D, represents an optionally substituted aryl group which can optionally contain heteroatoms, n1 is an integer of 1 to 3, m1 is an integer of 0, 1 or 2, m2 is an integer 0 or 1, M 1 is a metal with an atomic weight of greater than 40, L 3 is a monodentate ligand or a bidentate ligand, Y is —C(═O)— or —C(X 1 ) 2 —, wherein X 1 is hydrogen or C 1-4 alkyl, especially hydrogen and y is 0 or 1, especially 0; a process for their preparation, electronic devices comprising the metal complexes and their use in electronic devices, especially organic light emitting diodes (OLEDs), as oxygen sensitive indicators, as phosphorescent indicators in bioassays and as catalysts.
First claim
Opening claim text (preview).
